Abstract

L'INVENTION CONCERNE LA MESURE DE LA PRESSION OSMOTIQUE AU COURS D'UNE OPERATION DE SURFUSION. SELON L'INVENTION, DES GERMES DE CRYOHYDRATE SE FORMENT PRESQUE SPONTANEMENT DANS UNE PARTIE D'UN ECHANTILLON LIQUIDE QUI EST REFROIDI TRES AU-DESSOUS DE LA TEMPERATURE NORMALE DE SURFUSION SI BIEN QUE L'ENSEMBLE DE L'ECHANTILLON LIQUIDE SUBIT UNE FUSION DE FACON STATIQUE. LE DISPOSITIF PEUT ETRE REALISE AVEC UNE TRES PETITE DIMENSION ET PEUT COMPORTER UNE CELLULE A CIRCULATION. APPLICATION A LA MESURE DE PROPRIETES DES HUMEURS AU COURS D'EXAMENS CLINIQUES.THE INVENTION RELATES TO MEASURING OSMOTIC PRESSURE DURING A SURFUSION OPERATION. ACCORDING TO THE INVENTION, CRYOHYDRATE GERMS ALMOST SPONTANEOUSLY FORM IN PART OF A LIQUID SAMPLE WHICH HAS COOLED VERY BELOW THE NORMAL OVERFUSION TEMPERATURE SO ALTHOUGH THE ENTIRE LIQUID SAMPLE UNDERGOES FUSION STATIC. THE DEVICE CAN BE MADE WITH A VERY SMALL DIMENSION AND CAN INCLUDE A CIRCULATION CELL. APPLICATION TO THE MEASUREMENT OF MOOD PROPERTIES DURING CLINICAL EXAMINATIONS.
